There are many causes of headaches. Headaches can be acute, chronic or even migraines. Acute headaches come and go and can be caused by diseases or infections of the eyes, ears, nose, throat, teeth or sinuses. A blow to the head can cause a headache! Exposure to cigarette smoke, allergens or chemical fumes are sometimes triggers too. Certain drugs or use of alcohol, and dehydration may also be at fault.
Chronic headaches may accompany diseases, nerve dysfunctions, worry, brain tumors, and other physical, emotional, or psychosomatic disorders. Fevers and changes in metabolism can be possible causes too. Nerve conditions such as anger, fear, worry, excitement, disappointment, nervous tension, stress can cause headaches as bad or worse than those that have physical causes.
Migraines are the most extreme headaches and may begin in childhood or any time during adulthood. They may start with mood changes, fatigue, depression, thirst, hunger, nervousness or even lack of sleep. Twice as many women as men experience migraine and about half of all those who experience migraines report that it runs in the family.
Many people have headaches when giving up coffee, tea, and other addictive foods because the withdrawal process involves changes in the nervous system as well as release of toxins. This withdrawal process is often the cause of headaches.
